Ummm... if you read the article, the agents have already been outed. The ATF left "the list," behind. ahem... I'm just sayin'... And in response to your question- undercover is just an excuse for 'law-enforcement' to engage in illegal activity with a supposed, "nobler cause," of stopping illegal activity. Seems rather illogical. Encouraging law-breaking in order to stop and prevent law-breaking. Sounds like a government program to me. Why not just encourage values, morals and ethics in the youth of each generation? It worked until the early 60's. Funny-that's when government started getting too big to fail. And they want me to trust them for my health, retirement, and personal safety. Hmmm... I don't think so.
